The effects of moving computerized information systems from a centralized operation to distributed data processing

Abstract:

Investigates Distributed Data Processing (D. D. P. )and the effects the introduction of such a system would have upon Unicorn Lines. The problems with the existing information systems are that they preclude the production of timeous reports which are insufficiently detailed and involve operating management in accounting tasks. The systems are hard to change because they are fully integrated and there is inadequate documentation of the accounting packages. During the analysis of the trade creditors system it was found that D. D. P. would be a practical solution to many of the information problems. Distributed Data Processing is discussed in detail. The IBM System/34 is recommended for Unicorn Lines D. D. P. system after a number of other makes and models are examined. The central feature of the system is the display station which is situated with the user at the remote locations. Four System/34's are proposed with units being located in Durban, Johannesburg, Port Elizabeth and Cope Town. Various remote work stations will be attached to the units at these centres. The operating costs of a D. D. P. network is estimated at R150 000 per annum and it is doubtful whether such a system would make a significant number of staff redundant. D. D. P. will have a dramatic impact upon the information being mode available to management and upon the internal controls operating within the company. D. D. P. will, however, create a number of problems with internal control which will have to be solved through different procedural and organisational controls.
